  /* Measured on the live site: at .wrap 62rem the prose stopped a full 350px
     short of the section rules, so the right third of every page read as
     empty. 52rem / 40rem closes that to ~110px, which reads as a margin
     rather than as a missing column. Side effect, and a good one: the assay
     grid falls to two columns and each description gets room to breathe. */
